Yup, 625 hp > 545 hp. In a rolling race, you should win, assuming you start in your power band.

For the record, chip and midpipe on any year GTR (less than $1500 in upgrades) will be good for around 600 hp, and that would most likely be enough to reverse that outcome due to higher torque and wider power band on the GTR.

Love the M3, ive owned them for the last 14 years, but yall are a bunch of fanbois. Just bought a used GT-R and if put another 30k into it (still wouldn't approach 100k) id blast every M3 on the planet. Not that im going to, but that would be the result.

thats what every GTR owner says against most cars. corvettes m3s lambos etc

Actually I raced a 2013 GTR with a chip and midpipe and put 1-2 cars on it at one of the Shift-Sector roll racing events.

The vid is pretty bad as my passenger (some random girl at the event) held the camera straight ahead for some reason until we crossed the finish line - and then she panned over to where the GTR was at.

I haven't bothered to post it on YouTube because it's a crappy vid but am happy to do it.

Was that with the 625 kit that was shown in the last video that we were talking about or 650 that you have now? And with a midpipe or not? A midpipe would make a big difference on a boosted M3, and even a "625" kit M3 with a midpipe is not making 625 hp...probably at least 650.

What was your wheel hp in that video against the GTR and when your raced the GTR with chip/midpipe?

I'd bet a 600 hp GTR would beat an actual 625 hp M3 in a rolling race under most circumstances, due to broader power band and higher torque as I mentioned.

The GT-R is also a couple hundred pounds heavier.

No need for a broader power band when you are rolling because you can start at high rpm and shift at redline. The M3 is constantly above 6k rpm at each shift even with a manual transmission. No need to be at low rpm where low end torque is needed. But broader powerband and AWD is great for starting from a stop.

It was when I had the 625 kit. And yes I had a catless X-pipe (MRF) and Akra mufflers. My dyno's were in the 550-570 RWHP range STD. Both cars had 2 passengers. Roll-on speed around 40mph both starting in 2nd gear. I don't know the brand of tune/midpipe on the GTR.

True, although the roughly 300 lbs of weight difference narrows when you include about 100 lbs worth of supercharger kit and required fluids. And agreed that the power band is less of an issue in a rolling event like the one showed, where you are more likely to be able to be in the sweet spot, but it really does depend on the starting point. What if the rolling start is at 60? Not exactly the best starting point for an M3, as it would lug a bit in 3rd before getting on boil. It's definitely less of an issue with the GTR. The broad power band really helps no matter what speed or rpm you are at, not just off the line.

I think 550-570 rwhp is a lot more than 625 at the crank...that's more like 700.

Yeah... I'm no expert at roll racing besides a few friendly runs with friends. I've definitely haven't gone up against a GT-R. But bench racing numbers show it's pretty even. AWD almost becomes a disadvantage at higher speeds as the extra weight and AWD is not needed at high speeds.

I used to own Evos and off the line with launch control you'd jump about anything but at higher speeds even with the same HP, RWD cars start pulling harder.

I agree but the dyno was done in ideal conditions at STD on a dynojet. SAE would have been 540-560. Plus elevation at this dyno was like 100 feet. At the Shift-S3ctor event, the runs were done in the heat of the day and at altitude. I would have been making perhaps 525 RWHP SAE because the S/C can't compensate for DA's like a turbo car can. So 525 RWHP SAE is probably more like 625 crank.

thats fun. put your cute little supercharger on and fat tires and run into a modded GTR and you still get shit on

Are you on every forum I'm on?

Like UnaBomber, I also have a GTR. I drive an e93 M3 DCT as well.

Minor mods will make a GTR even more of a monster than it is stock. People are scared shitless when taken for a ride in my mildly modded GTR. For the 15K one would spend on a supercharger for the M3, you could make your GTR into a 9 second car that is very civilized. But they are VERY different cars, who just happen to both be liked by car people. Equally great cars.

Anybody getting a chance to own one should definitely allow surgical removal of a left nut to make it happen

Huh? GTR transmissions a pretty robust pieces of equipment. That warranty "issue" is in the distant past when a few people beat the crap out of their cars. 2012 and beyond have LC. I have owned an '09, '12, and '13 and never had one problem with any of them after 55000+ miles combined.

That is a little more comforting to know. I didn't know that pre 2012 GTRs didn't have LC.

I'm sure a lot of people beat the crap out of their M3s but BMW never had a policy of voiding their warranties when they found out they turned off their DSC. The whole warranty issue just wouldn't sit well with me if I ever had interest in purchasing a GTR.

These threads crack me up! Its always fun to start arguments on forums and let all hell break loose, right? Spices things up a bit. Once again comparing two completely different cars to each other and fighting about it lol

This one is for the guy who commented on blowing the doors off a 458 in his M3... I went from SC'd M3 to v8 R8. My M3 would blow the doors off my R8. Shit, my R8 is prob neck and neck with a stock M3 DCT. Do I care? F no! A week after buying the R8 I was offered a BJ by a beautiful 20 something year old in exchange for a ride in the R8. In the M3 all i ever got was a big "thumbs up" from dudes. Case closed

The amount of abuse a transmission and differentials take with traction control off on the GTR is nothing like the wheel spin that you get from turning off DSC. The GTR's transmission and diffs are a lot more robust than the M3 to handle the violence that launching the car does.

Even in a RWD M3, they won't let you do launch control on a DCT car multiple times in a row. If BMW allowed it, there will be a lot of broken transmissions.

Warranties get voided by practically all manufacturers if there's abuse.
I don't disagree that Nissan handled it poorly but most transmission failures were abused. Nissan should never of had the LC ability in the 2009 and things would have been fine.
